如何从Excel中读取A列数据

import pandas as pd

data = pd.read_excel('your_excel_file.xlsx', usecols='A')
column_data = data['A']

import org.apache.poi.ss.usermodel.*;

try {
    Workbook workbook = WorkbookFactory.create(new FileInputStream("your_excel_file.xlsx"));
    Sheet sheet = workbook.getSheetAt(0);  // 选择第一个工作表
    int columnIndex = 0;  // 列索引，从0开始
    for (Row row : sheet) {
        Cell cell = row.getCell(columnIndex);
        if (cell != null) {
            // 处理单元格数据
            String cellValue = cell.getStringCellValue();
            // ...
        }
    }
    workbook.close();
} catch (IOException e) {
    e.printStackTrace();
}

using ExcelDataReader;

using (var stream = File.Open("your_excel_file.xlsx", FileMode.Open, FileAccess.Read))
{
    using (var reader = ExcelReaderFactory.CreateReader(stream))
    {
        do
        {
            while (reader.Read())
            {
                // 读取指定列的数据
                string columnData = reader.GetString(0);
                // ...
            }
        } while (reader.NextResult());
    }
}
